IMPORTANT SAFETY INSTRUCTIONS
WARNING
Before use
The construction of this model is not isolated. People couldreceive electric
shocks and load cells, indicators and otherequipment could malfunction if
current from welding flows to this device during measurement.
Thoroughly verify that welding current will not flow to this device during
measurement before use.
If something abnormal occurs
Request repair from the retailer where you purchased the product.
Do not open the cover.
Never remove the cover from this unit. Doing so could cause malfunction.
Request inspection and repair from the retailer where you purchased the
product. Do not alter this unit. Doing so could cause malfunction.
Do not put foreign objects or water, for example, into the unit.
Do not place a container that holds water, for example, on top of this unit.
If liquid is spilled, for example, and enters the unit, this could cause
malfunction.
Do not use the unit with any power supply voltage other than that specified.
Do not use the unit with any power supply voltage other than that specified.
Doing so could cause malfunction.
CAUTION
Unsuitable placement locations
Do not place the unit in the following types of locations.
Doing so could cause malfunction.
- Near a power line
- Locations where strong magnetic fields exist or magnetic fields could occur
- Where static electricity or noise, (for example, from a relay) is generated
- Locations subject to temperatures exceeding the specified temperature and humidity ranges
- Locations subject to direct vibration or shock
- Locations subject to radiant heat from heat sources
- Locations exposed to dirt and dust
- Locations subject to severe temperature changes
- Locations that could freeze
- Locations where liquid, for example, could enter the unit as well as locations with high humidity where condensation could occur
- Locations where it might be exposed to smoke or steam, such as near a kitchen table or humidifier
- Unstable locations, including unsteady stands and tilted places
- Locations that are very humid or dusty
- Locations that are exposed to direct sunlight
When not using the unit for a long time
For safety, cut the power supply when not using this unit for a long time.
Do not operate a damaged unit.
Precautions for use
- This unit is not built to be water or splash resistant, and it cannot be used in conditions when the relative humidity is high. Moreover, use in atmospheres with corrosive gases should be avoided.
- Be careful to prevent water, oil and other substances from getting on the unit.
- Avoid use in conditions where condensation could occur.
- Connect cores to the load cell after discharging (eliminating) static electricity from your body.
- If the surrounding temperature changes suddenly, the values output by this device could become unstable, making accurate measurement impossible. (This could occur, for example, in a location blown by warm or cold air.)
- Conduct load calibrations periodically.
Using the load cell
- Conduct measurements with the entire bottom surface of the device in contact with the surface below it. Damage could occur due to impact loads and eccentric loads, for example, if measurement is conducted in a detached state. For placement during measurement, adjust the height and orientation using the handle. See “Precautions when placing loads on the unit” for details.
- Use the included cable to correctly connect an indicator, for example. Refer to “Electrical connection of load cell with built-in TEDS” for how to connect them.
Precautions when placing loads on the unit
-
Make sure the load is perpendicular to the surface to which this unit is attached.
-
Apply the load so that it is centered on the center of the unit. If the load is not centered (eccentric load), twisting, for example, and measurement errors could occur. This could even result in damage.
-
Be careful to avoid turning and twisting from lateral loads. This could cause troubles like those described in the previous item.
-
Be careful to avoid applying loads that exceed the rated capacity. In particular, use caution when there are vibrations because loads that exceed the rated capacity could occur due to sympathetic vibrations, for example.
-
If the load receiving area (spherical surface) is contacted by something that is at a different temperature and the load is increased, the values output by this device could become unstable, making accurate measurement impossible.
In such a case, wait until the temperature difference ceases to exist before measuring. -
When applying loads, have the bottom of the device contacting the installation surface.
Electrical connection of load cell with built-in TEDS
-
Connect as shown in the illustration below. Incorrect connections could result in inability to balance andin errors occurring in the output voltage when loads are applied.
-
Connect cores to the load cell after discharging (eliminating) static electricity from your body.
Connector attached
-
This unit has a built-in TEDS function. The orange and green cores in the cable and the F and G pins in the connector are wired for TEDS.
-
This unit does not support remote sense. See the operation manuals of indicators and strain amps that support remote sense for how to connect sensors with those units.
-
The shield is not connected to the main body of this product. For this reason, if grounding is necessary because of external noise or another issue, for example, arrange to ground the shield of the included cable to a part other than the body of this unit, for example.
-
Since the cable is directly connected to this unit, use a specialized cable to increase the length. (Please consult with us.)
-
When conducting insulation resistance tests, limit them to the red, black, blue and white cores. Do not apply to the TEDS cores (orange and green).
TEDS overview
TEDS (Transducer Electronic Data Sheet) is a memory chip that can
electronically read and write sensor-specific data. The TEDS built into this
unit has serial number, load cell rated output and manufacturer name data
recorded on it. By connecting an indicator that supports TEDS, the TEDS data
of the connected load cell will be automatically read and equivalent input
calibration will be completed. (For details, read the operation manual of the
connected indicator.) Refer to the connection diagrams in the “Electrical
connection of load cell with built-in TEDS” section as well as the operation
manual for the indicator being connected for procedures to make connections.
TEAC indicators and signal conditioners that support TEDS include the TD-01
Portable, TD-700T, TD-260T, TD-9000T and TD-SC1. For details, inquire at the
retailer where you purchased the unit. If not using the TEDS function, do not
connect the orange and green load cell cores. Moreover, take measures to
prevent the orange and green cores from touching other terminals. Data
recorded in TEDS are tested values from calibration conducted at room
temperature during inspection before shipping from our company. Load cell
output will be affected by the environmental temperature where used, even when
within the compensated temperature range established in the specifications.
Although load cell output is calculated from the calibration value saved in
TEDS, when the environmental temperature differs greatly from room
temperature, the temperature impacts increase on the zero point and the
output. For this reason, consideration of the effect on output voltage is
necessary. Output voltage changes will be within the specification range as
long as the unit is used at temperatures within the specification range.
Handling after use
- When moving this unit while it is attached, take protective measures to prevent it from being shaken or subjected to excessive external forces.
- When storing it, keep it in a dry place where it will not be exposed to water or oil, for example.
